The easy explanation would be that there are two small towns, Belgian Baarle-Hertog and Dutch Baarle-Nassau and that for some reason Baarle-Hertog is 5km across the border into the Netherlands. In fact it’s much more complicated than that. Baarle-Hertog isn’t just one area, it’s 21 separate little bits of Belgium each one surrounded by the Netherlands. They’re ‘enclaves.’ And then within those 21 enclaves there are nine ‘exclaves,’ little bits of the Netherlands, surrounded by Belgian territory, which in turn is surrounded by the Netherlands!

Wandering around the town/towns you’ll come across border markings as you cross from one country to another. The official ruling is that the border may run right through your house, but it’s the location of your front door which decides which country the house is in. They seem to have different street numbering procedures in the two countries so red-white-blue 33 in the Netherlands could be right next door to black-yellow-red 3 in Belgium. ▼

◄ Of course there had to be one door which precisely straddles the border. The town/towns have two town-halls, two Catholic churches, two fire departments and two police forces although both police departments are in the Belgian Town Hall. They do each have their own desk fronted by a flag so you know if you’re dealing with the Belgian or the Dutch police.
